The hopper magnet for an injection molding machine in the PLASTIC version is equipped with 4 magnetic tubes with a diameter of 22 mm, fitted with neodymium magnets with a pull-off force of 31 N per tube. The overall diameter of this magnetic separator is 200 mm and it offers temperature resistance up to 70°C (we recommend not exceeding this temperature to avoid gradual demagnetization). The total weight of the separator is 1.4 kg.
TEST METHOD
Magnetic induction measurement procedure
Measurements are performed using a standard gaussmeter at the point of the highest structurally available magnetic induction - at the pole pieces, i.e. at the lowest point of the arc of the magnetic circuit. We repeat the test 3 times, each time at a different point of the magnetic circuit, and calculate the average magnetic induction.
Pull-off force measurement procedure
We measure using a polished steel reference standard with a diameter of 10 mm and a height of 20 mm. Measurements are performed at the point of the highest structurally available pull-off force - at the pole pieces, i.e. at the lowest point of the arc of the magnetic circuit. We record the force at which the reference standard detached. We repeat the test 3 times and calculate the average pull-off force.
For your information, 10 N = approx. 1 kg.
The resulting pull-off force depends on many factors - e.g. the dimensions of the reference standard, the air gap between the reference standard and the tested magnetic circuit, surface finish of the reference standard, etc.
WARNING: The stated pull-off force values of some products were measured under ideal conditions given by the test environment. However, these values may change depending on the specific type of environment, where e.g. operating conditions and subsequent wear may affect the efficiency of the product. However, measurements were not performed for all products and in such cases these are only an estimate or an internal auxiliary calculation by the seller. The stated values must therefore be considered indicative and any deviations cannot be considered a defect within the meaning of Section 2095 and Section 2161(1)(a) of the Civil Code. To determine the exact pull-off force in a specific case, your own measurement is required. If the measured pull-off force values are not sufficient for you because they will not correspond to the stated values, you may use the guaranteed option to return the goods within 30 days under the conditions stated here: https://e-shop.magsy.cz/vraceni-zbozi/and purchase a stronger magnet. These 30 days are intended precisely for testing the goods; after this period, the seller may refuse the return.
